Patent attributes
A method for automated authentication of a user VoIP phone supported by a Private Branch eXchange (PBX) configuration server is provided. A VoIP phone or a VoIP supported device is configured for an automated authentication by a vendor. The authentication method does not require manual entry of authentication data by a user. The unique VoIP phone authentication data can be provided by the vendor in a form of a MAC address. Additionally, the vendor can assign a digital certificate (containing public and private encryption keys) signed by the vendor to the VoIP phone. In this case, the VoIP phone vendor serves as a trusted authority. Thus, the VoIP phone automatically connects with the configuration server and the authentication transformation server (ATS) and the address where the VoIP phone sends the authentication data upon connection to the network is determined by the ATS.
